Ordering shoes online is convenient, but the one thing you can't do is try them on first. That makes your foot measurement the most important number in the whole purchase. The good news is that measuring your foot at home is quick, free, and far more accurate than guessing from the size on an old pair. All you need is a sheet of paper, a pen, and a ruler or tape measure.
In this guide, we'll walk you through exactly how to measure your foot, how to read a shoe size chart, what to do when you fall between two sizes, and the common mistakes that lead to a poor fit. By the end, you'll be able to order walking shoes with confidence.
💡 Why measuring your foot matters
Shoe sizes are not as standardized as most people assume. The size printed on one brand's shoe can fit differently from the same number on another brand, and even two styles from the same brand can feel different. Materials matter too: a soft knit upper has more give than a stiff synthetic one, and a rounded toe box feels roomier than a pointed one.
Because of this, the size on your old shoes is only a rough guide. Your actual foot length, measured in inches or centimeters, is the one fixed point you can compare against any size chart. It also protects you from a few common problems: shoes that pinch at the toes, heels that slide with every step, and the hassle of sending a pair back because the size was off.
It's also worth remembering that feet change. Over the years, weight, activity level, and age can all affect how your feet fit into shoes. If you haven't measured your feet in a while, now is a good time to check.
🧰 What you need
- A sheet of paper that is larger than your foot (a standard letter-size page works for most adults)
- A pen or pencil
- A ruler or a flexible tape measure
- A hard, flat floor next to a wall (carpet can make it harder to get an accurate mark)
- The socks you usually wear with your walking shoes
📏 How to measure your foot, step by step
- Put the paper against the wall. Lay the sheet flat on a hard floor with one short edge pressed firmly against the wall. If it slides, tape the corners down.
- Stand on the paper. Place your heel against the wall, with your foot flat on the paper. Stand up straight and spread your weight evenly across both feet. Measuring while sitting can give a shorter result, because your foot lengthens slightly under your body weight.
- Mark your longest toe. Keep the pen upright and make a small mark on the paper at the tip of your longest toe. Many people assume this is the big toe, but for some people it's the second toe.
- Measure the length. Step off the paper and use the ruler to measure from the edge at the wall to your mark. Write the number down in both inches and centimeters if you can.
- Repeat with the other foot. It's very common for one foot to be slightly longer than the other. Use the larger of the two measurements.
- Measure the width (optional). Trace around your foot with the pen held upright, then measure the widest part across the ball of the foot. This helps if you suspect you need a wider fit.
📏 The best time to measure your feet
Measure in the late afternoon or evening. Feet tend to be a little larger at the end of the day after hours of standing and walking. If you measure in the morning, you might choose a size that feels fine when you try it on but becomes snug by evening. Since walking shoes are meant for all-day wear, it's smart to size for the end of the day.
📏 How to read a shoe size chart
Once you have your foot length, match it to a size chart. A good chart lists foot length in inches and centimeters next to each US size, so you can look up your measurement directly instead of guessing.
Use the chart that matches the style you're buying, because men's and women's sizes are on different scales. A men's size 8 is not the same foot length as a women's size 8. Every product page has a size guide with foot length in inches and centimeters for each US size, so you can check your size before you order. Men's styles cover US sizes 4 to 15, and women's styles cover US sizes 4 to 13.
Find your longest foot measurement in the table and look across to the matching US size. If your measurement lands between two rows, read the next section.

📏 What to do if you're between sizes
If your foot length sits between two sizes, choose the larger one. For walking, a little extra room at the front is almost always more comfortable than a tight fit. It leaves space for your toes to move naturally, helps when your feet swell a little during the day, and gives you room for thicker socks.
The one exception is if the larger size makes your heel slip when you walk. In that case, look for a lace-up style, where you can adjust the fit across the foot, or try a slightly different shoe shape. Our guide to slip-on vs lace-up walking shoes explains how each style holds your foot.
👣 How much space should there be at the toe?
A good rule of thumb is about a thumb's width, or roughly half an inch, between your longest toe and the front of the shoe when you're standing. Your toes should be able to wiggle freely. If your toes press against the front, or if the shoe feels tight across the top of the foot, try a larger size or a wider style.
👣 Do you need a wide fit?
Length is only half of the story. If your usual size feels fine in length but tight across the sides of your foot, you may be more comfortable in a wide fit style. Wide fit shoes are built with more room across the ball of the foot and in the toe area. Read our guide to wide fit vs standard walking shoes to see how to tell, and how to order wide styles online.
⚠️ Common measuring mistakes to avoid
- Measuring only one foot. Always measure both and go by the longer one.
- Leaning against the wall. Keep your heel touching the wall, but stand upright, and don't push your foot forward.
- Tilting the pen. Hold it vertically so the mark lines up with the tip of your toe, not the outline of your foot at an angle.
- Measuring over thick carpet. A hard floor gives you a flat, reliable surface.
- Relying only on the size of your old shoes. Shoes stretch and wear, and brands size differently.
- Ignoring the product's own notes. Always read the size guide and details on the product page, since fit can vary slightly between styles.

❓ Frequently asked questions
Should I measure both feet?
Yes. It's common for one foot to be slightly longer or wider than the other. Measure both and choose your size based on the longer foot.
What is the best time of day to measure my foot?
Late afternoon or evening is best, because feet are usually a little larger after a day of standing and walking. Sizing for that time of day helps your shoes stay comfortable for all-day wear.
Should I size up if I'm between two sizes?
In most cases, yes. A little extra room at the front is usually more comfortable for walking than a tight fit. If your heel slips in the larger size, try a lace-up style so you can adjust the fit.
Are men's and women's shoe sizes the same?
No. Men's and women's sizes are on different scales, so the same number does not mean the same foot length. Use the men's size guide for men's styles and the women's size guide for women's styles, shown on each product page.
How much space should I leave at the front of the shoe?
About a thumb's width, or roughly half an inch, between your longest toe and the front of the shoe while you're standing. Your toes should be able to move freely.
